    What's the Least Common Multiple (LCM) of 18 and 78?

    Answer

    LCM of 18 and 78 is
    234

    (Two hundred thirty-four)

    Finding LCM for 18 and 78 using GCF of these numbers

    The first method to find LCM for numbers 18 and 78 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

    LCM = (Number1 × Number2) ÷ GCF

    GCF of numbers 18 and 78 is 6, so

    LCM = (18 × 78) ÷ 6

    LCM = 1,404 ÷ 6

    LCM = 234

    Finding LCM for 18 and 78 by Listing Multiples

    The second method to find LCM for numbers 18 and 78 is to list out the common multiples for both numbers and pick the first one that matches:

    Multiples of 18: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270

    Multiples of 78: 78, 156, 234, 312, 390

    So the LCM for 18 and 78 is 234

    Finding LCM for 18 and 78 by Prime Factorization

    Another method to find LCM for numbers 18 and 78 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

    All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

    All Prime Factors of 78: 2, 3, 13 (exponent form: 21, 31, 131)

    21 × 32 × 131 = 234
